"The third and most important objectives were limiter assaults, in which the remote pilot deliberately exceeded the defined boundaries of controllability – such as angle of attack, sideslip angle and acceleration -- to see whether the airplane's computer could keep it flying steady...
Eight flight tests validated the programmed limiters and gave the team confidence that a robust, versatile, and safe control system could be developed for such an aircraft!" Read full.

Caption:NASA Dryden, Air Force Research Laboratory & Boeing Phantom Works team has finished its 1st phase of flight tests on subscale X-48B blended wing body aircraft at Dryden Flight Research Center. [*Start: 2006]
-NASA's Gray Creech writes: #Crash-resistant... My kind of plane. :#
"Tests with the X-48B will continue later this year, after a new flight computer is installed and checked out. The next series of flight tests will focus on additional parameter identification investigations."
"NASA has a second hybrid wing body aircraft, the X-48C, which it has modified for a noise profile even lower than the X-48B's, and is preparing for test flights to investigate other controllability factors." Read.
